Abstract
A film feeding apparatus and method are disclosed that have improved operability and reliability using magnetic reading devices and read magnetic data frame by frame, store them in RAM and set flags indicative of the presence or absence of the magnetic data while a film is unwound. If a frame whose magnetic data has not been read yet is judged to be present with reference to the flags in RAM, the magnetic data are read and stored in RAM and the flags are set while the film is rewound. If the frame whose magnetic data has not been read yet is judged again to be present with reference to the flags in RAM even after the film is rewound, an operator is notified by means of a display. If the operator gives a command to reread the magnetic data by means of a keyboard, the magnetic data are reread again after the feeding speed of the film is changed.
